PUMP FOR DRILLED WELLS.

SPECIFICATION forming part of Letters Patent No.521,720, dated June 19,1894.

I Application filed March 14, 1893.

To all whom it may concern:

-Be it known that I, DAVID LIPPY, a citizen of the United States,residing at Mansfield, in the county of Richland and State of Ohio, havelnvented certain new and useful Improvements in Pumps for Drilled Wells;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to WhlCh it appertains to make and use the same, reference being hadto the accompanymg drawlngs, and to the letters vof reference markedthereon, which form a part of this specification.

My invention relates to improvements in pumps and the objects of myinvention are, first, to construct a double acting force-pump, to beused in drilled-wells and for other purposes, the said pump to takewater at the downward stroke of the piston as well as at the upwardstroke of the same, and supply a steady and continuous stream of waterfrom the d scharge-pipe; second, to make a novel, cheap, durable, andefficient means for the 2 5 purpose stated In the accompanying drawingsFigure l is a side elevation of my improved pump showing the barrelintact, the discharge-pipe and connecting-rod broken away. Fig. 2 is alongltudinal sectional view of same, showing the 1nter1or constructionof the same. Fig. 3 is a transverse sectional view taken in line a-aFig. 2 showing the construction'of the upper valves and ports, the portsshown in dotted lines. Fig. 4. is also a transverse sectional View takenin line 00-00 Fig. 2 showing the construction of the induction ports andvalves.

slmilarletters refer to similar parts th roughout the several views.

In the accompanying drawings A indicates a pump barrel which may beconstructed of gas-pipe or any metal tubing.

B. indicates a cap which is attached to the lower end of the pump-barrelbyscrew threads. The said cap is provided with the center opening 0. Thesaid opening is provided with the tongue valve D, the said valve beingof common construction.

. E indicates a perforated ring or flange forming part of thecap B.

F indicates a plunger which is composed of Serial No. 465,894. onmodel.)

a solid metal head and provided upon the upper and lower ends, withleather cup-shaped suckers G and H.

I indicates an inner pump barrel which is smooth upon the inside and inwhich operates the pump-plunger F. The said inner tube is much smallerthan the outer tube allowing a water space J around the outer peripheryof the inner tube. The lower end of the said tube rests upon the edge ofthe perforated hinge E. The upper end is secured within a socket K,forming part of the upper casting L. The lower end of the upper castingis provided with the threaded coupling M which connects the upperportion L and the lower portion A together, clamping the inner tube Irigid in the position shown.

N indicates a hollow tubular partition which forms part of the uppercasting L, The said partition is of the same diameter as the tube I. Itis so constructed as to form a hollow chamber 0 and in the bottom isformed the upper induction ports P. P. The said ports are provided withtongue valves R placed upon the under side. These valves are for thepurpose of supplying the pump-barrel with Water when the plunger is inits downward motion. A tubular stem S extends from the center upwardfrom the center of the lower partition, to the top of the inductionopening 0, and is provided upon the upper end with the stuffing-box T.This forms a guide for the connecting rod U. The upper partition V isprovided with discharge-ports W and W.

A circular tongue valve X is secured upon the top of .the said ports.The said casting L is reduced at the top and provided with femalethreads and in which is secured the discharge pipe Y.

It will be readily seen that the operation is simple and efficient. Itwill be presumed, that the pump-barrel is full of water, the wa terhaving passed into the barrel through the opening 0 and through theinlet-ports R-R the plunger is at its extreme throw the upward motion ofthe plunger forces the water through the port Z and valves W into thedischarge-pipeV atthe same time the lower portion of the barrel isfillingwith water supplied through the lower v'alve D the downward Imotion of the plunger forces the water through the perforations d upwardinto the space J and through the valve W into the discharge pipe.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

A submerged double acting pump consisting of an outer shell whichcommunicates at its upper end with a discharge pipe and has its lowerend closed bya cap provided with a cen tral valve and an upwardlyextending perforated flange surrounding said valve, a tube arrangedwithin the shell and resting at its lower end upon the perforated flangeat the bottom thereof, a tubular partition arranged near the upper endof said tube and forming a chamber which opens through the outer shelland communicates with the inner tube 7 DAVID LIPPY.
